Most commercially available conductive oxides such as indium doped tin oxide (ITO) and fluorine doped tin oxide (FTO) are expensive. This has made local production of alternative oxides necessary. This work demonstrates local production of transparent conducting stannous oxide (SnO) film via thermal decomposition of stannous chloride dihydrate (SnCl2·2H2O). The films were then characterized optically and electrically using UV/VIS spectrophotometer and four point probe, respectively. The thickness of the film increased linearly with precursor mass. While the sheet resistance and optical transmittance decreased, the optical absorbance increased with increased thickness. Average optical transmittance ranged between 85% and 94% and the sheet resistance lies between 62.89 Ω/sq and 84.57 Ω/sq. With these characteristics, the deposited film will be useful for optoelectronic applications.
